Can You Actually Trade Size at 100x? Stock Futures Leverage Tiers and Position Limits Explained
Exchanges put big leverage numbers on their banners.
The banner does not say how much you can actually hold at that number, or how much margin a bad fill eats once leverage multiplies it.
On MEXC stock futures, the first answer is a tier table where 100x sits in the smallest tier; this guide reads it for three contracts and works the second answer through a $100,000 AAPL order.
Key Takeaways
- On MEXC stock futures, the leverage you select sets the largest position you can open, and that cap shrinks as leverage rises.
- As of September 22, 2026, SNDK's tier 1 caps a position at 80,000 contracts (80 shares' worth) at any leverage above 50x, with a 0.40% maintenance margin rate.
- TokenInsight's August 2026 report found MEXC was the only sampled venue that consistently supported meaningful position sizes at 100x as of July 29, 2026, though not the largest cap at every tier.
- Maximum leverage is set per contract and can be lowered in volatile markets or around earnings; positions above a lowered ceiling can be closed but not increased.
- The same slippage difference takes a bigger share of margin as leverage rises: at 20x, every 1 basis point of slippage costs 0.4% of margin per round trip.
- In the worked example, 10,000 USDT at 20x survives a 4% drop, while the largest 100x position on the same contract is liquidated after a 0.6% drop, before fees and funding.
What is a position limit in futures, and why do leverage tiers shrink it?
A position limit is the largest position, in contracts or USDT, that MEXC lets you open at the leverage you selected on a given stock future, and it shrinks as leverage rises because MEXC sorts position sizes into risk-limit tiers, each with its own maximum leverage and maintenance margin rate.
The higher the leverage setting, the smaller the cap, and the bigger the position, the higher the maintenance margin rate it needs to stay open.
Your maintenance margin rate follows your position size, not your leverage, so a large position at 10x can carry a higher rate than a small one at 100x.
A risk-limit tier is not one of the speculative position limits the CFTC and US futures exchanges set for whole markets; it is a margin rule for one position.
How much can you hold at 100x on a MEXC stock future?
On a MEXC stock future, 100x sits in tier 1, the smallest tier: as of September 22, 2026, MEXC's contract data capped that tier at 80,000 contracts on SNDK, 20,000 on MU and 75,000 on SK hynix stock futures, and tier 1 covers every leverage setting above 50x, including 100x.
The tiers below come from MEXC's public futures contract API on September 22, 2026.
Contract | Tier | Max position (contracts) | Shares' worth | Max leverage | Maintenance margin rate |
SNDK | 1 | 80,000 | 80 | 200x | 0.40% |
SNDK | 2 | 600,000 | 600 | 50x | 1% |
SNDK | 3 | 4,500,000 | 4,500 | 20x | 2% |
SNDK | 4 | 11,600,000 | 11,600 | 10x | 5% |
MU | 1 | 20,000 | 200 | 200x | 0.40% |
MU | 2 | 100,000 | 1,000 | 50x | 1% |
MU | 3 | 250,000 | 2,500 | 20x | 2% |
MU | 4 | 1,000,000 | 10,000 | 10x | 5% |
SK hynix | 1 | 75,000 | 75 | 200x | 0.40% |
SK hynix | 2 | 145,000 | 145 | 50x | 1% |
SK hynix | 3 | 1,250,000 | 1,250 | 20x | 2% |
SK hynix | 4 | 5,000,000 | 5,000 | 10x | 5% |
On all three contracts, 100x and 200x share tier 1, so choosing 200x does not shrink the cap.
Read SNDK's ladder downward: each step from 200x to 50x, 20x and 10x multiplies the cap, from 80 shares' worth to 600, 4,500 and 11,600.
Tiers are set in contracts, so the USDT figure on the risk-limit page moves with the share price, and MEXC can change the tiers.
Confirm the current tiers on the contract's risk-limit page or trading page before you size an order.
For another contract, follow MEXC's guide on how to view risk limit details.
What did TokenInsight find about 100x position capacity?
TokenInsight found that position limits tighten as leverage rises at all five centralized exchanges in its August 2026 equity perpetuals sample, and that MEXC was the only venue that consistently supported meaningful position sizes at 100x across the five stock futures checked, as of July 29, 2026.
The snapshot in TokenInsight's August 2026 report covered SOXL, SPCX, INTC, SNDK and SK hynix.
MEXC did not post the largest cap at every tier: at lower leverage on SPCX, one of the other sampled venues published a larger limit.
MEXC's depth and slippage results in that report and every other 2026 report are collected in the guide to how to judge crypto exchange liquidity.
What is the maximum leverage on MEXC stock futures?
Maximum leverage on MEXC stock futures is set contract by contract and shown on each trading page: as of September 22, 2026, MEXC's contract data listed a 200x maximum on SNDK, MU and SK hynix, while the AAPL stock futures trading page showed a 1x to 100x range as of November 4, 2026.
MEXC's guide to how to trade stock futures puts the ceiling at up to 200x as of September 2026.
Maximum leverage and position limit are different numbers: one sets the margin per dollar of exposure, the other caps the dollars you can hold.
The ceiling can move, since MEXC's risk-limit rules let it lower maximum leverage in volatile markets, and positions above a lowered ceiling can then be closed but not increased.
On November 2, 2026, for example, MEXC cut the AAPL ceiling to 20x for three hours around its earnings release, then restored 100x.
The same can happen outside US market hours, when MEXC may cut the leverage on new orders, as the guide to trading stock futures on weekends explains.
For which stocks are listed as futures in the first place, see MEXC's stock futures coverage by market.
How is leverage on MEXC stock futures different from margin on traditional stock futures?
Leverage on MEXC stock futures is a dial you set, up to the contract's ceiling, on a perpetual contract margined in USDT or USDC with no expiry date, while a traditional stock future carries a fixed expiry and an initial margin set by the exchange, so its leverage is whatever that margin implies.
Most traditional futures are closed out before their delivery date, as the CFTC's basics of futures trading explain.
Setting | MEXC stock futures | Traditional stock futures |
Expiry | None, though MEXC can settle early around corporate events | Fixed expiry date |
Margin | Follows the leverage you pick | Initial margin set by the exchange |
Leverage | Your choice, up to the contract's ceiling | Implied by the margin |
Size cap | Risk-limit tier for your leverage | Exchange position limits |
Stock futures are also one of three ways to trade US stocks on MEXC, beside RealStocks and tokenized stocks.
Why does SOXL get tighter limits?
SOXL gets tighter limits at several venues in TokenInsight's August 2026 sample because the fund is itself a 3x leveraged ETF, so a futures position on SOXL stacks exchange leverage on top of the fund's own leverage, and the effective exposure to the semiconductor sector is the product of the two.
The fund's issuer states the 300% daily target on its 3x semiconductor ETF page.
TokenInsight treats SOXL as a special case for this reason, and MEXC still listed a 100x tier on SOXL in that July 29, 2026 snapshot.
Why does slippage matter more when you trade with leverage?
Slippage matters more with leverage because it is charged on the full notional value of the order but paid out of the margin you posted, so the same slippage difference is a bigger share of a smaller margin: at 20x, every 1 basis point of slippage difference costs 0.4% of margin per round trip.
Slippage cost in dollars equals order size times slippage in basis points divided by 10,000, and a round trip pays it twice.
Share of margin equals the round-trip difference divided by margin, or leverage times the slippage difference in basis points times 2 divided by 10,000.
At 20x that is 20 × 1 × 2 ÷ 10,000 = 0.4% per basis point.
In MEXC's own comparison of order-book snapshots against four other major centralized exchanges, averaged over three days to October 28, 2026, simulated slippage is the average of a buy and a sell against the snapshot mid-price, excluding fees and funding; each MEXC figure is set against the best of the four on that asset and size, and every figure is one side, so a round trip is twice it.
In MEXC's October 28, 2026 comparison, a $100,000 AAPL order showed $1.66 of simulated one-way slippage cost against $14.27 on the best of the four, a saving of $12.61 or 88%.
A round trip at market saves 12.61 × 2 = $25.22.
Open the same $100,000 AAPL position at three leverage settings, an illustrative scenario inside the 1x to 100x range the AAPL trading page showed as of November 4, 2026, and only the margin behind it changes.
Leverage | Margin behind a $100,000 AAPL position | Round-trip slippage saving | Share of margin |
5x | 20,000 USDT | $25.22 | 0.13% |
10x | 10,000 USDT | $25.22 | 0.25% |
20x | 5,000 USDT | $25.22 | 0.50% |
At 20x the margin is 100,000 ÷ 20 = 5,000 USDT, and 25.22 ÷ 5,000 = 0.50%, four times the share at 5x.
With the order size fixed, leverage changes neither the slippage nor the fees, only the margin behind them.
Your order size changes the story.
Keep the margin fixed and raise leverage instead, and the order grows, so slippage must be measured again at the larger size.
The saving does not scale in a straight line.
A single snapshot is not a promise of the same saving on every future open and close.
The full table of six round-trip scenarios at 20x is in the guide to fees, slippage and total trading cost.
Why the same order fills worse as it grows is covered in how slippage grows with order size.
How do you pick a tier without getting liquidated?
Pick the tier by the size you actually want to hold, not by the leverage you would like to use, because the cap decides which leverage settings are open to that size, and the tier's maintenance margin rate sets how far price can fall before liquidation.
Check that size against the order book depth at the touch as well, because a position the tier allows can still be bigger than the book will absorb without moving the price.
Worked example: 10,000 USDT on SNDK at 20x versus 100x
Assume SNDK trades at 800 USDT, a round number rather than a quote, and the position uses isolated margin.
MEXC's long liquidation price is maintenance margin minus position margin plus exposure, divided by shares, where maintenance margin is exposure times the tier's rate.
At 20x, 10,000 USDT of margin lands in tier 2; at 100x, the SNDK cap of 80 shares means 10,000 USDT cannot be deployed at all.
Step | 10,000 USDT at 20x | Largest 100x position |
Exposure | 10,000 × 20 = 200,000 USDT (200,000 ÷ 800 = 250 shares) | 80 × 800 = 64,000 USDT (80 shares, the cap) |
Margin | 10,000 USDT | 64,000 ÷ 100 = 640 USDT |
Tier and maintenance margin rate | Tier 2, 1% | Tier 1, 0.4% |
Maintenance margin | 200,000 × 1% = 2,000 USDT | 64,000 × 0.4% = 256 USDT |
Liquidation price | (2,000 - 10,000 + 200,000) ÷ 250 = 768 USDT | (256 - 640 + 64,000) ÷ 80 = 795.2 USDT |
Drop from 800 USDT | 4% | 0.60% |
The 20x position survives a 4% drop, while the largest 100x position on the same contract is liquidated after a 0.6% drop.
Both prices exclude liquidation fees and funding, which move the real trigger a little closer to entry.
If losses hit a large position, MEXC's laddered liquidation steps it down a tier before closing the rest.
If the Futures Insurance Fund cannot cover a shortfall, the ADL mechanism for futures shortfalls can close profitable traders on the other side.
The Futures Insurance Fund absorbs liquidation shortfalls for the futures market as a whole and does not cover traders' own losses.
That math, not the banner, is why 100x is a tool for small positions rather than a default.
FAQ
What is the maximum leverage on stock futures?
Maximum leverage is set per contract; SNDK, MU and SK hynix showed 200x on September 22, 2026, and MEXC's stock futures tutorial says up to 200x as of September 2026.
Why can't I open a bigger position at 100x?
Because 100x sits in tier 1 with the smallest cap; lowering leverage moves you to a tier with a larger cap and more margin per dollar.
What is a risk limit tier?
A band of position sizes sharing one maximum leverage and one maintenance margin rate, published per contract on MEXC's risk-limit page.
What is maintenance margin?
The minimum margin a position must keep to stay open: position value times the tier's maintenance margin rate.
Does the position limit change with the market?
Yes; the USDT cap moves with the share price because tiers are set in contracts, and MEXC can adjust tiers, leverage and margin rates in volatile markets.
Is 100x available on every stock future?
Not necessarily; maximum leverage is set contract by contract and can change, so the trading page is the only reliable answer.
What happens if I exceed a tier?
An order above the cap will not open at that leverage until you lower it, and if MEXC tightens a limit after you are in, you can close but not add.
Does higher leverage increase slippage?
Not when the order size is fixed, because slippage is charged on notional value; raising leverage on a fixed margin means a larger order, so measure slippage again at that size.
Is a position limit on MEXC the same as a CFTC position limit?
No; a MEXC risk-limit tier is a margin and liquidation rule for one position, while a CFTC speculative position limit caps the contracts one trader may hold in a US futures market.
Conclusion
The leverage number on the banner is a margin setting, and the tier table is the size setting that decides what you can do at 100x.
The same slippage difference takes a bigger share of margin as leverage rises, so size the position before you touch the slider.
Read the live tiers for your contract, and note the date.
